Abstract :
The scale transform has been proposed and applied to 1-D signals in applications such as speech processing, biological signals and machine vibration analysis. This paper describes some results of the scale transform use in some practical applications, in particular for image denoising. Our preliminary work indicates that under many circumstances denoising in the scale domain appears more effective than in the Fourier domain
